Definitive Audio Koala 15A (Unit)

The KOALA Series: A New Generation of Active Speakers Focused on Performance and Mobility

With the KOALA series, DEFINITIVE AUDIO unveils a range of active speakers featuring a modern design and a clear philosophy: to offer a sound system that is simultaneously powerful, reliable, versatile, and easy to transport. Available in three sizes (10-inch, 12-inch, and 15-inch), the range adapts to most sound reinforcement contexts, from small events to more energetic sets requiring greater low-end presence. The KOALA 15 model is positioned as the ideal option when seeking more breadth and impact while maintaining quick setup.

A 15-inch Active Speaker for DJs, Musicians, Conferences, and Stage Monitors

The DEFINITIVE AUDIO KOALA 15 targets users who need a 2-way active speaker capable of covering many applications: music playback for DJs, clear voice reinforcement for speaking, sound support for live bands, or event sound reinforcement indoors and in sheltered outdoor spaces. Thanks to its size, it is particularly suitable for setups where a more prominent bass is desired without multiplying the number of speakers.

A notable advantage: all three versions of the series can be used in stage monitor position. The KOALA 15 is thus suitable both for front-of-house and monitoring, depending on your setup and projection needs.

Power, Control, and Reproduction: KOALA's Approach for Direct and Effective Sound

Bi-amplification Class D + Class AB: Efficiency and Precision

The KOALA 15 features bi-amplification combining Class D for bass (efficiency and dynamics) and Class AB for treble (finer response and detailed sensation). This architecture aims for balanced reproduction, with an energetic low end and a more defined high end, useful for vocals, cymbals, leads, and overall mix presence.

High-Quality Drivers and Controlled Directivity

Its 15-inch woofer with a 3-inch voice coil is designed to handle power and move air efficiently, while the 1.35-inch tweeter ensures clarity in the high frequencies. The 90deg x 60deg dispersion allows better control of coverage, practical for targeting the audience and limiting less useful zones depending on room configuration.

Simple Adjustments: Efficiency in the Field

In real-world situations, quick adjustment is as important as power. The KOALA 15 includes Bass and Treble correction knobs as well as a volume level knob, to tailor the sound to a voice, denser music, a reverberant room, or monitor use. The front panel power indicator (blue LED) also facilitates visual monitoring during performances.
